(mostly cuz of weather) The loss or compromise of anything, navigation or other, reduces margins and confidence. And there are rules, policies, and laws that establish certain minimums to keep an overconfident pilot from setting up a dangerous scenario, especially for passenger operations. When minimums are not attainable, the pilot will divert to an alternate airport that should have been selected before takeoff, and should still have 30 minutes of fuel left when he arrives at the alternate. | |

As "Pilots already factor out any signal that doesn't correlate with the others" it would appear that interference with GPS would remove one important signal, significantly reducing redundancy and the margin for other failures. That could mean the need to do things differently, such as divert to where conditions or equipment are more suitable. Is that a valid conclusion for me to draw? | |
